The product or overall change in time for 8 weeks will be 29.33 minutes.
What is a statement?A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.
Given:
After one week, Greg's watch has lost 11/3 minutes. If the watch continues to lose time at the same rate, we can say that the change in time is 11/3 minutes per week.
According to given question we have
(11/3 minutes/week) x (8 weeks) = 29.33 minutes
Therefore, the product or overall change in time for 8 weeks will be 29.33 minutes.

How to determine the statement as an algebraic expression?Statement 1
The statement is given as
Ramona has 4 less than 6 times as many one dollar bills as Rita has
Let the number of one dollar bills owned by Ramona be x and the number of one dollar bills made by Rita be y
So, the interpretation of the statement is
x = 6y - 4
Hence, the algebraic expression of the statement is x = 6y - 4
Statement 2
The statement is given as
Robert made 3 more than twice as many baskets as Billy did in the basketball game.
Let the number of baskets made by Robert be r and the number of baskets made by billy be b

James wants to have earned $8,388 amount of interest in 22 years. Currently he finds that his
annual interest rate is 7.34%. Calculate how much money James needs to invest as his principal in
order to achieve this goal.
The money James needs to invest as his principal in order to achieve this goal is $ 5, 197. 67
How to determine the amount
The formula for simple interest is expressed as;
Simple Interest, I = PRT/100
Where:
P is the principal amountR is the rateT is the timeSubstitute the values
8388 = P × 7. 34 × 22/ 100
cross multiply
161. 48 P = 838800
Make 'P' the subject of formula
P = 838800/ 161. 38
Divide through
P = $ 5, 197. 67
Thus, the money James needs to invest as his principal in order to achieve this goal is $ 5, 197. 67

If an arrow is shot upward on the moon with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t−.83t2.
(a) Find the average velocity over the given time intervals:
(1) [1,1.5]
(2) [1,1.1]
(3) [1,1.01]
(4) [1,1.001]
(b) Find the instantaneous velocity after one second (to the nearest hundredth).
(1) m/s
(2) m/s
(3) m/s
(4) m/s
(b) m/s
The 58 m/s initial velocity of the arrow with height, y = 58•t - 0.83•t², gives;
(1) 55.925 m/s
(2) 56.257 m/s
(3) 56.3317 m/s
(4) 56.33917 m/s
(b) 56.34 m/s
How can the average and instantaneous velocity be calculated?Initial velocity of the arrow = 58 m/s
Height of the arrow is; y = 58•t - 0.83•t²
The above kinematic equation can be analyzed as follows;
(1) The height at t = 1 is found as follows;
y = 58 × 1 - 0.83 × 1² = 57.17
Height at t = 1.5 s. is y = 58×1.5 - 0.83×1.5² = 85.1325
Average velocity = ∆y/∆tWhich gives;
Average velocity = (85.1325-57.17)/(1.5-1) = 55.925
The average velocity in the interval [1, 1.5] is therefore;
55.925 m/s(2) [1, 1.1]
Height at t = 1.1 s. is y = 58×1.1 - 0.83×1.1² = 62.7957
Which gives;
Average velocity = (62.7957-57.17)/(1.1-1) = 56.257
The average velocity is 56.257 m/s(3) [1, 1.01]
Height at t = 1.01 s. is y = 58×1.01 - 0.83×1.01² = 57.733317
Which gives;
Average velocity = (57.733317-57.17)/(1.01-1) = 56.3317
The average velocity is 56.33 m/s
(4) [1, 1.001]
Height at t = 1.01 s. is y = 58×1.001 - 0.83×1.001² = 57.22633917
Which gives;
Average velocity = (57.22633917-57.17)/(1.001-1) = 56.33917
The average velocity is 56.33917 m/s(b) The equation for the instantaneous velocity is found as follows;
v = dy/dt = 58 - 2×0.83•t
After 1 second, we have;
t = 1
v = 58 - 2×0.83 × 1 = 56.34
The instantaneous velocity at t = 1 seconds is 56.34 m/s

What are variables?
A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common symbols used for variables!
How do we describe variables in word form?
When we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable).
In this case "The sum of a number" has no definite correlation to a number, therefore, it is automatically considered a variable.
Then, since it says "The sum" we know we are adding. Adding what? We are adding an unknown term to the number 7.
Henceforth, the answer is x + 7.

12.3 is equal to 123 ones.
80 tens is greater than 6 hundreds.
43,200 is less than 50 thousands.
60 hundreds = 6,000
(a) 45 tens is equal to 450. :- True
(b) 12.3 is equal to 123 ones. :- True
(c) 80 tens is greater than 6 hundreds. :- True
(d) 43,200 is less than 50 thousands. :- True
(e) 60 hundreds = 6,000 :- True
Consider the first statement,
45 tens are equal to 450
So, 45 tens mean 45 times 10 is written as:
45 × 10 = 450
Hence, it's true.
Consider the second statement,
12.3 is equal to 123 ones.
Now, 123 ones is equal to 123 times 1.
123 × 1 = 123
Hence, the statement is true.
Consider the third statement,
80 tens is greater than 6 hundreds.
Now 80 tens = 80 × 10 = 800
Now, 6 hundreds = 6 × 100 = 600
Now, 800 > 600
Hence, the statement is true.
Consider the fourth statement.
43,200 is less than 50 thousands.
Now, 50 thousands = 50 × 1000 = 50,000
We know,
50,000 > 43,200
Therefore, the statement is true.
Consider the fifth statement,
60 hundreds = 6000
Now, 60 hundreds = 60 × 100 = 6000

What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

A toilet manufacturer has decided to come out with a new and improved toilet. The fixed cost for the production of this new toilet line is $16,600 and the variable costs are $67 per toilet. The company expects to sell the toilets for $157. Formulate a function P(x) for the total profit from the production and sale of x toilets.
The function P(x) for the total profit from the production and sale of x toilets is P(x) = 90x - 16600
How to formulate a function P(x) for the total profit from the production and sale of x toilets?The given parameters are
Fixed cost = 16600
Variable cost = 67 per toilet
Cost of toilet = 157 per toilet
Let the number of toilets be x
So, the cost function is
C(x) = Fixed cost + Variable cost * Number of toilets
This gives
C(x) = 16600 + 67x
Also, we have the revenue function to be
R(x) = Cost of toilet * Number of toilets
This gives
R(x) = 157x
The function P(x) for the total profit from the production and sale of x toilets is
P(x) = R(x) - C(x)
So, we have
P(x) = 157x - 16600 - 67x
Evaluate
P(x) = 90x - 16600
Hence, the function P(x) for the total profit from the production and sale of x toilets is P(x) = 90x - 16600
